Volume content
So far, the ideal-tight typical cross section is usually considered at the evaluation of constructions with the help of hygrothermal simulation. Usually…
The airtightness of office buildings influences energy use and thermal comfort. A leaky office building is likely to have a high use of energy and thermal…
In this work the air leakage database of French single family dwellings, available at the CETE de Lyon (Centre d’Études Techniques de L’Équipement), has…
Already in the year 1983, the general basis paper for noting air tightness, which was elaborated by the Swedish construction council for the AIVC, pointed…
The basic statistics of airtightness test results collected since 2002 in the Czech Republic are presented. The test results are compared with the limit…
Two studies have recently been performed to evaluate the current form of the Delta-Q test for duct leakage. In the first study 19 new homes in Wisconsin,…
There is increasing recognition of the importance of quantifying the airtightness of large commercial and residential buildings. Often these tests must be…
An object reconstructed for residential purposes approved to be not sufficiently air tight. With methods that are generally known as inappropriate, it was…
When two adjacent residential buildings in Ludwigshafen were fully renovated in 2005/2006, energy efficiency was a focal point from the very beginning. One…
With the background of different climates within Norway it was interesting to show the resulting differences in energy demand for the same typical office…
The combination of air tightness measurements and thermography introduces new application areas for both practices: the building thermography will be…
The developed method uses Radon as natural tracer gas, which appears everywhere in the nature hence in all buildings as well. Contrary to blowerdoor-…
Attic moisture control is one of the key issues addressed by the hygrothermal design of wood-frame houses. In general, exfiltration and natural ventilation…
Although there have been built about 20 sports halls with passive house standards by now, where the principles of residential houses and first experiences…
As we increase energy requirements on ventilation, it is essential to assess the real performance of these systems on site, both for energy savings and IAQ…
Air tightness of the building envelope contains important initial data for hygrothermal design and energy calculation. This study presents and analyses…
Experiences of the past years showed that it is possible to achieve a considerably better air flow rate in large buildings than it is targeted by the…
From the year 2007 the buildings must have energy efficiency calculations, which requirements arenow part of Building Code Book. This is based on European…
In order to determine the causes of SHS (Sick House Syndrome), a field survey on indoor air quality and health conditions of occupants has been conducted…
The airtight version of a building envelope has been accepted as a structural engineering challenge in by construction workers in Germany. At the same time…
